Referring to FIG. 1, a semiconductor integrated apparatus 10 in accordance with an embodiment may include a processor 110 and a plurality of functional blocks 120-1 to 120-N which operate under the control of the processor 110. The semiconductor integrated apparatus 10 may be, for example, an SoC (system on chip) in which the plurality of functional blocks 120-1 to 120-N with various functions are implemented as one chip. In order for the semiconductor integrated apparatus 10 to be applied to an embedded system, at least one of the plurality of functional blocks 120-1 to 120-N may be an interface functional block capable of communicating with a host apparatus or a slave apparatus.

Functional blocks 120-1 to 120-N which are integrated into one SoC have different operating characteristics such as operating frequencies and voltages. Even in the same functional block, operating characteristics may vary depending on input power, and thus, it is necessary to trim an operating voltage according to the input power.

In an embodiment, each of the plurality of functional blocks 120-1 to 120-N may be an electronic system selected among functional blocks such as a CPU (central processing unit), a GPU (graphics processing unit), an NPU (neural network processor), a CP (communication processor), each core of a mufti-core processor, a PMU (power management unit), a CMU (dock management unit), a system BUS, a memory, a USB (universal serial bus), a PCI (peripheral component interconnect), a DSP (digital signal processor), a wired interface, a wireless interface, a controller, an embedded software, a codec, a video module, a graphics core, an audio system, a volatile memory, a nonvolatile memory and a memory controller.

In an embodiment, the processor 110 may include a voltage trimmer 20.

The operating characteristics of each of the functional blocks 120-1 to 120-N may vary depending on input power of an apparatus to which the semiconductor integrated apparatus 10 is mounted, that is, a host apparatus. For example, an operating voltage characteristic in a first host apparatus operating with a first power supply and an operating voltage characteristic in a second host apparatus operating with a second power supply may be different from each other.

Therefore, operating voltage characteristics of the respective functional blocks 120-1 to 120-N depending on an input power level of the host apparatus are measured through a wafer level test, and candidate trim values for trimming the operating voltage characteristics are determined and are stored in a storage space in the voltage trimmer 20. Input power information may be obtained when the semiconductor integrated apparatus 10 is powered on, and trim values for the respective functional blocks 120-1 to 120-N may be selected from the candidate trim values corresponding to the input power information, The selected trim values may be transferred to the functional blocks 120-1 to 120-N, respectively.

That is, the voltage trimmer 20 may be configured to store candidate voltage trim values of each of the functional blocks 120-1 to 120-N, the candidate voltage trim values being classified according to an input power level.
